I have a Cairn supplement that I wrote solely for the purpose of including it in charity bundles. I do not want to sell or otherwise distribute this item in any way, save as an item in charity bundles. Currently, this is possible on Itch by changing the Public Access Settings to “Disable new downloads & purchases”. That allows me to add the item to bundles, but disables the purchase button. Anyone who buys a bundle that includes the item is able to download it, but no one is able to buy or download it separately.
AFAIK, this is currently not possible on RPG Trader, which requires a Pricing Tier before publishing, and requires Pricing Tiers to be either Free or Paid. There are workarounds that can get me part-way to the functionality, but not altogether exclude downloads or purchases. The simplest way, it seems to me, would be a pricing tier option that disables pricing and limits downloads to owners.
I’d be open to other solutions, if better ones are available.
